The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern.-

Be it known'that we, Ooannnius F. HOBNBEGK ,and. WILLIAM J. OARNS, ofthe village of Slaterville, Tompkins county, New York, have invented anImproved Snow-Plow, of which the following is a specification.

Our object is to make a railroad snow-plow, adapted for use at alltimes, and especially useful in removing deep banks in cuts-or otherplaces where ordinary forms avail but little.-

The nature of our invention will be apparent as we describe it.

Figure 1 is' aside view of our plow, on a piece of track, and

Figure 2 is a view of the bottom of our plow when- The timbers or partsvD' are placed at a distance apart equal to the gauge of therailroad-track, and form rails for the wheels G to run 011, as will bepresently seen.

Near the inner sides of the rails D, and parallel to them, aresecuredtwo other similar pieces, D, which, with the parts D, make adouble track on top of the car A.

On one or both of these'tracks is the platformcar E, with a fiat andsmooth upper surface, as wide, or a little wider than the track of therailroad. i

The platform E is supported by the small wheels F on the rails on themain car.

To the forward end of the platform-car E is hinged the extension E,which extension is supported by the wheels G, whichv rest on therailroad-track rails or are drawn on the main car-rails I) at pleasure;and to aid in this retraction the inner rails D"project a little furtherforward than the rails D, that the flange of the wheels G shall becaught in the space between the car-rails D D'before the wheels G leavethe road-rails AtHis a. dumping-plow, of any required shape, held by therear brace J to the locomotive or to the main car-frame, and is mainlysupported by the pieces I, connected with the main car-frame, and havinga roller at K under the point.

A rack, L, is fast to the center of the platformcar E, on its underside, and-on the shaft of the wheels B is a pinion, B, which, by thecord M and lever M, at the option of the engineer of the locomotive, isthrown into gear with the rack L, or by any of the well-known devicesfor the purpose.

A bent lever, N-a device so well-known as to need no fulldescription-moved by the stop 0 on the extent-ion E, or other convenientplace, throws the pinion out of gear as soon as the platform is dumpedof snow. I

The stops P Q It also limit the motion of the platform-car on the maincar, and maybe made of any suitable shape, and placed at any convenientpoints and T is a lever, arranged so as to hold the platform forwarduntil the cord M is pulled, which releases the platform, as well asmakes the changes for dumping the platform-car of snow.

At U is one of the two knives or cutters that part the snow, so that itlies on the platform.

V is a spring, (fig. 2), retracting the lever N; and

V, a spring aiding the meshing of the pinion at the forward end of therack L.

Figure 2 has the same letters. The operation of our snow-plow is asfollows \Vhen running in light snows, it is set as seen in fig. 1, andthe snow is caught by the front E and slides on the top of the platformto the. hood H, by

which it'is thrown oft on each side of the railroad track.

But when our plow encounters a bank or other deep snow that cannot bethus thrown off, the locomotive is stop'ped with the part E and a E,loaded up to the hood-plow H, when the engineer backs to a place wherehe can dump the load on E E; he then, while still backing, pulls on thecord M and puts the pinion B in gear with the rack L, which retracts theplatform-car under the plow H until it is unloaded, when the pinion isput out of gear.

.The platform resumes its place, as seen in fig. 1.

The repetition of this action clears the bank, out, or other deep place.

We intend to use our plow with or without the oxtension E, as convenientor necessary.

The other'advantages and uses of our invention are apparent to thoseskilled in the art towhich'it appertains.

Ola-tins;

1. The plow-car A, with a single or double track on the top of it, theplatform-car E, and unloading hood or plow H, operating together,substantially as described.

2. The just named plow, when further combined with the anteriorroad-attachment E, substantially as set forth.

3. The arrangement of the rack L on the platform-car, and the pinion Bon the shaft of the wheels B, the cord M and lever M, and the stops orcams required for these parts, for'the purpose of moving andcontroling'the platform-car E on the main car A, substantially as setforth.

4. The whole consisting of the platform E, and anterior hinged part E,hood-plow H, rack and pinion L, and cord M, combined and arranged so asto operate substantially as set forth.
